EXTENSIBLE PEDAL CONNECTION FOR ADDRESSING'TEACHINES.

Application filed July 1,

This invention relates generally to automatic means for tripping the driving clutch of a power-driven mechanism and means under control of the operator for afterwards resetting the same so that the machine may continue in operation until the clutch is again automatically thrown out. More specifically it embodies an improvement on t e invention described and claimed in our U. S. Patent No.1,518,912, granted. December 9, 1924, and is herein illustrated in the form in which it has" been applied to an addressing machine of the type covered by U. S. Patent No. 1,256,509 granted to E. D.

Belknap, February 19, 1918. V

Our present improvement embodies one device l'or overcoming the noise and jar created in the operation of certain previously patented apparatus of this general character by inserting an extensible connection from the pedal system to the clutch throw out mechanism and having the automatic selecting device (not shown) permit this connection to be extended when one of the pre 2 determined cla s of cards is fed out of the magazine to printing position, the pedals remaining locked in depressed position until released by the operator. One form of apparatus embodying our present invention is illustrated'in the attached three sheets of drawings, in which,

Fig. 1 is a side elevation of the pedals and their connections, parts being shownin section, and others broken away,

Fig. 2 is a planview.

Fig. 3 is an elevation of the extensible connecting rod on a larger scale to illustrate its mode of operation, and

Fig. 1 is a section on'line H of Fig. 1.

'llhroughout the drawings like reference characters indicate like parts. 1, 1, are the uprights of the main frame of the machine supporting a table carrying the operating parts uch as the card handling, printing and selective mechanism. (not shown), said uprights being held together by side bars,

one of which is shown at 3, and-cross bars such 2 and 23 shown broken away. 10

(Fig. 1) repre='ents diagrammatically a clutch on the main driving shaft of the machine which is usually of the one revolution type, being automatically thrown out at the end of each cycle of operation of the ma- 1926. SeriatNo. 119,826.

chine by the throw-out cam 72 when the lat ter s swung up on its pivot 7 3 by the spring 7 1 lnto the position shown in full lines in Fig. 1. 17 is a pedal rigidly mounted on the bent crank shaft 18, pivoted on the side bars 3, at 18 (Fig. 2), and connected by an ex tensible connecting rod 616'to the'throwout cam 7 2. This connecting rod or link is otatelescoping character, the lower portion 6 being connected to the upper portion 16, by a pin and slot arrangement consisting of the pin 11, screwed into the connecting rod section 16, and engaging slot 9 in the connecting rod section 6. These two rod sect ons 6 and 16 are held in non-eXtendedposition shown in full lines in Figs. 3 and 4b the hook-shaped latch 12 pivoted at 13 on the upper link section 16, and normally engaging the pin 14 on the lower linksection 6. The upper end of the latch 12 is widened out into sectorshape and provided with a spring-pressed ball or plunger 21, adapted to engage either one of the recesses 21, or 21", in the latch holder 22, screwed to the upper link section 16 and located in the plane of said latch, as best shown in-Fig. 4.

Obviously, when the latch 12 is in the position shown in full lines in Fig. 3 with the ball 21 engaging the notch 21 and the hooked end of'the latch engaging pin 14, the telescoping link 616 is held in non-extend-- ed condition and moves as a unit when pedal 17 is pressed downward, thereby pulling down the throw-out cam 72 and permitting the clutch 10 to remain in engagement. This permits clutch 10 to drive the machine continuously. If, however, while said pedal 17 is held in depressed position, the latch 12 is rotated I in clockwise direction so that its hooked end clears pin 14, the spring 74; will pull up the throw-out earn 7 2 and the upperv section 16 of the extensible connecting rod,

which is pivoted to 72, as far as the movement of the pin 11 in slot 9 permits, and the driving clutch;10 will be thrown out of engagement at the expiration of that cycle of the machine operations, the link section 16 and latch 12 then assuming the dotted line position shown in-Fig. 3. v

The particular apparatus for thus freeing latch 12 from pin 11 here illustrated comprises the link 26 pivoted at 15 to the upper portion of the latch and at its other end pivoted to the core 27 of the solenoid 28. Ob-

If, after the connecting rod has beenthus elongated,the pedal 17 ispermitted to rise, latch 12 can be caused to reengage-pin 14 and thus hook up the connecting rod sections 6-416 innon-extendedposition so that whenpedal 17 is again depressed, cam72 will be also pulleddown and clutch 10 will be allowed to go into mesh and the machine will start running again.

The apparatus for thus relatching connecting rod 6 -16 in shortened condition here illustrated comprises the link 26, one

end of which ispivoted at 15 to the upper portion oflatch 12, while its other end is pivoted at 37 to the crank arm 36 on sleeve 35 which is loosely mounted on cross bar 23 of the main frame, which cross bar is of cylindrical shape, said sleeve 35 having operatire connections to reset pedal 29, also pivoted on cross bar 23. The preferred form of operating connections between pedal 29 and sleeve 35 comprises a second sleeve 30 to which pedal 29 is rigidly connected and which is also loosely mounted on shaft 23 and provided with a projecting lug 38 cooperating with lug 40 projecting from the adjacent end of sleeve 35. Obviously, when pedal 29 is pressed downward and lugs 38 and 40are in contact, the rotation of sleeve 30 will be transmitted to sleeve 35, and link 26* will be pulled to the left (lookingat Fig. 1), thus slightly rotating latch 12 in a counterclockwise direction back into the full line position shown in Fig. 3.. This will pullout solenoid core 27 into the position shown in Fig. 1, cause the latch to engage pin 14 (assuming that pedal 17 is in raised position), and reset the parts with the connecting rod 6 16 in non-extended position so that whenpedal 17 is again depressed the main clutch will be"disengaged and the machine again started into operation.

1 In a machine organized to run contin uously until the selective apparatus or other automatic device trips the latch 12 and stops the machine, it may be desirable to provide means for locking the pedal 17 in "depressed position so that the operator need not hold his foot upon it or otherwise positively maintain it in depressed position by continuous effort. In the apparatus described this is accomplished by the swinging lock member 20 carried by sleeve 30 and adapted to engage a lug 41on pedal 104 which is pivoted at 105 to pedal 17 and overhangs the laterally projecting stud 106 carried by pedal 17. This pedal 104 (called the skip pedal in machines of this character), when depressed, carries down with it pedal 17 and, so long as lock 20 is in line with lug 41, will be held by 20 in depressed position and also hold down pedal 17, thus permitting the machine to run on. When, however, the operator presses down on reset-pedal 29, he will swing lock 20 out of line with lug 41, as shown in full lines in Fig. 1, and thereupon spring 7 V (Fig. 2), which is anchored onbent cross bar 2 of the main frame and at its lower end connected to pedal 17,. will raise said pedal 17, telescoping connecting rod 616 back into shortened position ready 1 for re-engagement of latch 12 with pin 14, which latch is simultaneously-swung into such re-engagement with said pinby the same or continued movement of reset pedal 29 through the train of connecting mechanismterininating in link 26 as before explained. Upward motion of the pedal 17 also carries up skip pedal 104 through the action of stud 106.

Spring 19 connected at its upper, end to the crank arm 39 on sleeve 30, and at its lower end to skip pedal 104, tends to rotate sleeve 30 in a clockwise direction, (looking at Fig. 1) whenever skipfpedal 104 is depressed, with the result that as soon as lug 41 on saidpedal gets below the lower end of swinging lock 20, the latter is snapped over into dotted-line positionshown in Fig. 1, so that when the operator thereafter moves his foot froni'pedal 104 it is still held down by lock 20. i i

Lock 20 is prevented from swinging too far in this resetting operation and is held in position to register with lug 41 by lug 34 on the under side :of sleeve 30 striking against lug 33, carried by stop collar 31 held in adjusted position 'on shaft 23 by thumbscrew 32. Collar 31 also prevents sleeve 30 from sliding on the shaft 23 away from sleeve 35, and sleeve 35 is held against inot-ion-in the opposite direction by collar 42.

107 is a link pivoted by screw pin 25 to skip pedal 104 and operating a card skipping mechanism not shown. but similar to that described in our before mentioned patent. i

The lower section 6 ofthe'eiitensible con necting rod 616 is fasten-ed on tbelever of pedal 17 by screw 5 and pins 3-SZ Operation of our invention when applied to an addressing machine of the type described incur before mentioned patent, and here shown in part, is as follows: The selective device is set 'so as to be actuated by apparatus controlled by link 10? into a position which will disable the printing apparatus. Both pedals will be held down by lock which is swung by spring 19 into dotted line position shown in Fig. 1 to en gage lug 11 011 pedal 10 1. This also raises reset pedal 29 into dot-and-dash line position, but, as lug 38 then simply moves away from lug 40, no motion is transmitted to sleeve and latch 12 is allowed to remain in its engaged position so that connecting rod 6+16 is held in telescoped or non-extended condition and cam 72 is thereby held down out .05? operative position by pedalli' as shown in dot-and-dash lines in Fig. 1. This leaves clutch 10 free to engage and the machine rnns on, feeding and skipping all stencil cards, until another one of the class to be used in printing reaches printing position.

Thereupon the selective mechanism energizes solenoid .28, latch. 12 is tripped, spring T4 pulls cam 72 up into operative position. and the clutch 10 is disengaged at the end of that cycle, leaving that stencil card. in printing 1 position. The operator then presses down reset pedal 29, which trees lo-"l'c2O irom lug l1, permitting skip pedal 104 and also printing pedal 1710 rise under the pull of springs 7 and 19. Thetr-ipping of latch 12 by its clockwise movemenhnlaove described, has also given a clockwise movement to sleeve and moved lug 40 over into contact with lag 38. Consetpiently the above described depression oi reset pedal 29, producing a counter-cloclnvise rotation of sleeve 30, has

lective apparatus in the previously described operations. The pressure on pedal 1'? should only be momentary so that cam 72 may rise again and be in position to stop the machine at the end of that cycle. After the printing operation the operator again presses down ship pedal 104i, resetting lock 20 and starting the machine again on its operation of tecthn and sin 1) 111 cards until another card the class to be used in printing is fed into printing position and latch 12 has been again tripped by the selective apparatus in the manner first described.

The main advantage oi th s invention arises from the fact that the stoppage ot the machine 1s effected by the selective device through the movement of only the small,

light weight parts 16 and 72, and without the creation of any objectionable noise or shoot: of heavy moving parts. lt i s only after the operator has depressed reset pedal 2-9 that pedals 104- and 17 are allowed to rise, and any shock which might then be caused by asudden stoppageat the upper limit of their movements can be avoided by the operator holding his other foot over pedal lO 'l so astocushion thisupward move,

ment. v c lVhile we have shown and described our invention applied to an addressing machine ot' the particular type above referred to, it is eyident that modified forms of the ipventionmight be applied to other forms; of addressing machines and to other classes of power-driven mechanism wherever itis desirable to autoi'natically stop the same withoutproducing objectionable noise and shock, and. this can be done without depart ing from the underlyingprinciple of our in vc ntion as the same has been set forth in certain of the appended claims.
